These Nokya Heavy Duty Headlight High Beam H1 Wire Harnesses have been designed to be plugged into your Honda S2000's stock wiring. Aftermarket bulbs or not, your Honda S2000 stock lighting H1 harnesses are not designed to handle extended periods of use, or operation in adverse or severe conditions. To address this, Nokya offers these H1 Heavy Duty Headlight High Beam harnesses as a cheap and relatively easy upgrade to your stock Honda S2000 electrical system. They work as replacements for damaged stock H1 harness plugs, or as complete upgrades as a precautionary measure against harness plug burnouts (which can permanently damage your Honda S2000 headlight housings). These Honda S2000 Heavy Duty Headlight High Beam H1 Wire Harnesses also help to handle the increased demands of aftermarket Headlight High Beam bulbs, Nokya brand or otherwise. Each set consists of 2 harnesses.
